HOKSESHOE.

Application filed June, 5,

T all whom it may concern:

Be it known that'l, HENRY PAAR, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented a new and useful Horseshoe, of which the following is a specification.

My invention relates to improvements in horseshoes provided with removable callss, and the objects of my invention are, first, to provide a horseshoe whereto may be attached calks oi various shapes to suit difllerent purposes and conditons; second, to provide a horseshoe wherein the calks which. are worn dull may he removed and new calh's substituted, and this being accomplished without the aid of the farrier; third, do do away with the frequent removal of shoes from the horses 'ieet necessary in the case of the ordinary horseshoes, and to thus avoid the consequent injury to the hoofs; fourth, to eheapen the cost maintenance oi horseshoes in use and to accomplish other objects which will be readily apparent to those skilled in the art. I attain these objects by the device illustrated in the accompanying drawing, in which Figure 1 is a perspective view from the bottom side of a horseshoe embodying my improvement, one of the removable calks being separated or removed from the call: flanges. Fig. 2 is a longitudinal section .through the shoe, retaining pin and calk, said view being taken on a plane indicated by the line 2--2 in Fig. 3. Fig. 3 is a transverse section through the shoe, calk flanges, retaining pin and calk, said view being taken on a plane indicated by the line 33, in Fig. 2. Fig. e is an elevation. of one of the removable calks.

Throughout the several views similar reference numerals indicate similar parts;

The numeral'l indicates a horseshoe having the usual general contour and provided at the front with the outer and inner calk flanges 2 and 3 respectively, and also provided at the back with the outer and inner call; flanges 4 and Said calh flanges are preferably integral. with the main portion of the horseshoe, and arrangement is preferably made for two heel callts and one too call: longer than the heel calks. The arrangement of the call; flanges and the means of attaching the call'ts thereto is the same for both heel and toe talks, a detailed description of the construction and arrangement of Specification of Letters Patent.

' parallel surfaces will closely engage t parts of one of the heel ealks will therefore be sufiicient.

The calk flanges 4 and 5 are provided with inner plain surfaces parallel with and spaced from each other in such way that the said .0 sides 6 and 7 of the call: 8. Extending from one calh flange to the other calk flange is the retaining pin 9, the said pin being 'n'e'l'erably located about midway between the ends of the call; flanges and away from the suriace'oi the shoe 1. This pin accomplishes two pur poses, the one to strengthen and support the cal-k flanges and tie them together, the said pin being headed down upon the outside of each flange, and the second to retain the call: in position as hereinafter described.

The call: is provided with the rounded opening which communicates with the base of the call; by means of a slot, said slot being slightly narrower than the diameter of the opening as best shown in Fig. 4. The pin 9 is of such diameter that it exactly fits the opening 10. In placing the said calk properly in the call: flanges, the base is arranged between the parallel surfaces of said flanges and the contracted slot communicating with the opening 10 is brought immediately on top of the pin 9. The calk is then given a sharp blow with a hammer or other instrument whereupon the edges of the said contracted slot spring sufficiently to allow them to pass the pin whereby the pin becomes located in the opening 10, and the said pin closely fitting said opening and the calk flanges closely engaging the sides, the said calk is held rigidly in place.

The ends of the calks are notched; at the base as shown at 11--11, which notches permit a cold chisel to'bc inserted into said notches for the purpose of prying the calk out of the calk flan when it is desired to replace the callrs with new ones.

it will be understood that the calliesl'iown in the drawing are provided with 'sharp treads for use upon icy pavements and the like. Other forms of treads may be provided upon the calks of the same shape as to their bases as those shown in the drawing, and such calks will be interchangeable with those shown.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is

llU

1. The herein described horseshoe comprisingashoe proper, calk flanges integral with said shoe proper, said calk flanges arranged in pairs, each pair having parallel cated in said rounded openings.

2. The herein described horseshoe comprising a shoe proper, call: flanges integral with said shoe proper, said calk flanges arranged in pairs, each pair having parallel inner surfaces spaced from each other and a retaining pin extending between said call: flanges, calks provided with rounded openings and slots narrower than the diameter of said openings extending from-said rounded olpenings through the bases of said callrs, tie said calks arranged between the calk flanges with the retaining pins, located in said rounded openings, and notches inthe ends of said ca :5. p

3. In a device of the character described, a shoe proper, callr flanges arranged thereon.

in pairs and a round retaining pin extending 30 between the two flanges of each pair, calks'. provided with faces ada ted to closely engage the inner surfaces 0 the calk flanges, said calks also provided with openings of the same diameter as the diameter of the re- 35 taining pins and slots extending from said- 0 enings through the bases of said calks t e said slots being of less dimension than the diameter of said openings.

4, In a horseshoe of the class described, a shoe pro er in combination with calk flanges arrange thereon in pairs and integral therewith, call: retaining pins arranged between the calk flanges of each pair, calks rovided with openings and slots narrower 518,11 said 3 openings and the said calks arranged between t 1e said. calk flanges with the said retaining pins arranged in the said openings of the calks, substantially as and for the purposespecifled.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.

HENRY PAAR.
